- w. B. FENN Q CORING AND TRIMMING MECHANISM Fiied Dec. 29, 192;

IN V EN TOR 9 .4 ATTORNEY described. The aw members are each pivotallymounted on adjacent portions of the respective plates 7. The other plate6, which is held clamped to plate 7 by the screw 5, is provided with aflange portion 11 and the lip 1:2. The flange portion 11 and the lip 1:2form a cutting annular recess between the lip 12 and the top of the baseplate 1, it being understood that the plate 7 is countersunk relative tothe base plate 1, at the edge of the orifice or opening through thecenter of the base plate 1. Held by the plate (3 with its flange and lip11, 12 respectively, forrotary movement in the annular space abovedescribed, is what I will term the actuating ring 13. This ring;contains a projection in the form of a pawl illustrated at 1 1, which,when engaged, serves to rotate the ring in one direction, in the formshown counterclockwise, and substantially opposite thereto are providedtwo rounded projections 15 and 16 which, when rotated, serve to rotatethe ring in the opposite direction, namely clockwise. The ring is alsoprovided with three downwardly projecting; lugs 17 spaced equi-distantlyaround the same, which lugs carry rigidly therewith pins 19. The jaws,as above noted, consist of the members 8, 9 and 10, the upper endsthereof being cut away and the respective members being' pivoted at theapproximate ends of their cutaway portions, so that when the jaws arerocked so that the upper ends thereof move towards each other, thecontacting edges serve to cut the material encompassed therebetween fromthe rest of the body, whereas the opposite ends thereof are at a maximumdistance apart. It is understood that the edges of these respectivecutting members 8, 9 and 10 are sharp-edged to form in effect clippers.I

Each of the jaws 8, 9 and 10 provided with a cam groove 21. All of thejaws are similarly constructed with the cam groove 2-1 extending in anupwardly direction throughout the width of the jaw, but it will bereadily apparent that when the three jaws are placed opposite each otherin normal central. position the cam grooves 2i tend in oppositedirections with respect to any two thereof. The pins 19 which form partof the rotatable ring; 13 extend through the cam grooves 21 respectivelyof the members 8, 9 and 10,"so that when the ac tuating ring is rotatedin one direction, due to the cam action effect by the an-o'ves 21 andthe pins 1.9, the jaws are opened, and vice versa.

It will be seen from the foregoing that the coring device thus fardescribed is substantially the. same as that forming the subjectmatterof my co-pending application. above identified, and differs therefromlargely in I the pr vision'of three jaw members in place of two thereof.

and 10 are knife-edged, as above described.

The corer assembly, in the form selected for illustration, is thenactuated. by the chain which engages the pins a, as described, un til itis desired to cut out the core of the article, at which time theactuating ring 13 is rotated mechanically or otherwise by means of thelugs 15, 16, to the position shown in Fig. 4e, whereby the core is cutout and allowed to drop through the open and extended bottoms of the jawmembers 8, 9 and 10. lVhen it is desired to again open the jaws, the lug14 is mechanically or otherwise engaged to rotate the actuating ring ina counterclockwise direction back to the position shown in' Fig. 8.

It has been found in the practical operation of the corer, that whilethe corer operates efliciently and entirely satisfactorily, itsefficiency can be increased by employing three coring blades instead of2. It has also been found that in some instances, in handling aparticular product of an exceedingly adhesive skin, the core tends toadhere somewhat to the skin, and in other products it is advisable ordesirable to trim the product being operated upon to remove blem ishes,skin adhesions, etc., in the same oper ation with the coring thereof.

7 I therefore have shown and will now de scribe a trimming device usedin connection with the corer hcreinbefore described.

The trimming device consists of a plurality of tootlredged blades 30,preferably provided with their teeth'on a bent portion of the bladesbent normally with right angles with respect to the body thereof, asclearly illustrated in Fig. 2. These blades are positioned between thecoring knives 8, 9 and 10 andthe ring 13, and are pivotally supported atthe edge of their approximate centers to the end of supporting arms 31permanently secured to the body 1, as shown best in Figs. 2 and 8. Eachof the trimming blades 30 is provided with a groove 32, which islikewise inthe nature of a cam groove and through which the pins 19 ofring 13, which upon rotation of ringv 13 actuate the corer blades 8, 9and 10, likewise actuate the blades 30. As shown, I prefer to employthree trimming" blades, one blade for each coring blade. it will bereadily understood that by proper y proportionmg and controlling" thedirection of the cam groove.

32 of the respective trimming blades, the

same may be made to operate at any desired time with respect to theoperation of the corer. For example, the trimming bladesmay be made tooperate about the time of complete closure of the edges of the corerblades, so that trimming will be effect ed at the time the tomato orother vegetable or fruit is removed from the device.

Many modifications and changes in detail will readily occur to thoseskilled in the art Without departing from the spirit and scope of myinvention as defined in the claims, and having shown and described astructure embodying the principles thereof, What I claim as new anduseful and of my own invention, and desire to secure by Letters Patentis 1.
